Sergey Vladimirov <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from Sergey Vladimirov <[email protected]> --- There is a very serious problem with offset parameter. "offset" parameter means not key/value offset, but rather row number offset. Because of that it is possible to create queries that creates full-index-scans using large offset values. Current state-of-art is usage of values anchor, not pages (even in mediawiki API). It may be entity id anchor or claim id anchor.
